The continued speed improvement of serial links and appearance of new communication technologies, such as ultra-wideband (UWB), have introduced increasing demands on the speed and power specifications of high-speed low-tomedium resolution analog-to-digital converters (ADCs).This paper presents the design of high speed and ultra low power comparator of a 4-bit ADC. The comparator used is Threshold Inverter Quantization (TIQ) consuming less than 145μW power with the input frequency of 1GHz and... Topics: SoC, CMOS, ADC, TIQ.
The advancement in IC technology rendering area optimized and fast ICs is primarily attributed to MOSFET scaling theory. The scaling theory sustained the Moore’s law till the channel size reached the nano-meter regime. The issues in MOSFET due to scaling aggregated and resulted in leakage currents and high power dissipation making the transistor unreliable. The research has been done to find a potential replacement for traditional CMOS and to sustain Moore’s law. Many ... Topics: CMOS, GNRFET ALU, Power Dissipation
In the ultra low power end of design spectrum when performance is of secondary importance, digital subthreshold logic circuits are more applicable than the regular MOS logic. In this paper, we propose two different subthreshold logic families: 1) variable threshold voltage subthreshold CMOS (VT-Sub-CMOS) and 2) subthreshold dynamic threshold voltage MOS (Sub-DTMOS) logic. Both these logic families have comparable power consumption as regular subthreshold CMOS logic along with superior... Topics: Subthreshold logic, Sub-DTMOS, VT-Sub-CMOS.

We present a new circuit topology for potentiostats that interface with three-electrode amperometric electrochemical sensors. In this new topology, a current-copying circuit, e.g., a current mirror, is placed in the sensor current path to generate a mirrored image of the sensor current. The mirrored image is then measured and processed instead of the sensor current itself. The new potentiostat topology consumes very low power, occupies a very small die area, and has potentially very low noise....

Process variation is an difficulty in designingreliable CMOS mixed signal systems with high yield. Tominimize the variation in voltage gain due to variations inprocess, supply voltage, and temperature for common transconductance-based amplifiers, we present a newcompensation method based on statistical feedback of processinformation. We further apply our scheme to two well knownamplifier topologies in the sun-micron CMOS process asdesign examples—an inductive degenerated low-noiseamplifier... favorite ( 2 reviews ) Topics: CMOS analog integrated circuits, process compensation, process variation, self-biasing.

As Technology progress deeper into submicronCMOS, traditional analog circuits face problems that arenot to be solved purely by analog innovations. Instead,new architectures are being proposed which take advantagesof the relatively cheaper of the digital circuits to augment orimprove the diminishing performance of the analogcircuitry. The conventional approach performs the design of14 bands CMOS frequency synthesizers with spur reductionfor MB-OFMD for analog circuits which have highdistortions...

The real universe signals are all analog in nature. Therefore, an analog to Digital converter is needed to transmit effectively the analog signals to digital. A low power and low voltage necessities are consideredprominent issues in the digital domain, as the channel length of MOSFET compresses lower than 0.25 sub-micron values. These trends flaunttopical challenges in ADC circuit design. This paper is an endeavour to contrive a flash analog to digital converter for low-power and high speed...

A new charge pump, which can operate with very low supply voltages, is proposed. The MOS transistors are used as charge transfer switches (pass gates) to eliminate the effect of the threshold voltage in the pumping gain of each stage. The MOS switch of each pumping stage is controlled by the output of a dynamic inverter established in the same stage; however, the control voltage of that inverter is derived from the preceding stage. This forward control scheme considerably reduces the risk of... Topics: CMOS, DC-DC converter, charge pump, low voltage, high efficiency
With the increase in demand of high fidelityportable devices, there is more and more emphasis layingdown on the development of low power and high performancesystems. In the next generation processors, the low powerdesign has to be incorporated into fundamental computationunits, such as adder. CMOS circuit design plays a crucial rolein designing of these computation units (like adder andmultiplier) so if there is any optimal way to reduce the powerdissipation in CMOS circuits then it will...
